I am a banker. As per State Bank regulation more than 5 yrs old cars cannot be financed.
You can get personal loan to finance this car. However clean personal loan amount will not exceed PKR 500,000/- and even if a bank is willing to take that much exposure on you with security the interest rate will be very high. 18% plus.
You may get a loan against some investments if u have any (such as govt. saving certificates, NIT units, shares etc)
Or get financing against property. That way you can secure a cheaper rate and get large amounts.
Another good option (a bit expensive than standard leases) is if you have another car at home (not older than 5 yrs) then you can get financing against that. The bank will sale & lease back that car to you and in return you get cash and drive car at the same time. Checkout UBL for this offer.
